Binge eating is when a person eats a much larger amount of food in a shorter period of time than he or she normally would. During binge eating, the person also feels a loss of control.
A binge eater often:
- Eats 5,000–15,000 calories in one sitting
- Often snacks, in addition to eating three meals a day
- Overeats throughout the day
Binge eating by itself usually leads to becoming overweight.
Binge eating may occur on its own or with another eating disorder, such as bulimia. People with bulimia typically eat large amounts of high-calorie foods, usually in secret. After this binge eating, they often force themselves to vomit or take laxatives. For more information, see: Bulimia
The cause of binge eating is unknown. However, binge eating often begins during or after strict dieting.Last Updated: 08/22/2017
What To Look For
Most people with binge-eating disorder are overweight or obese, but you may be at a normal weight. Behavioral and emotional signs and symptoms of binge-eating disorder include:
- Eating unusually large amounts of food in a specific amount of time, such as over a two-hour period
- Feeling that your eating behavior is out of control
- Eating even when you’re full or not hungry
- Eating rapidly during binge episodes
- Eating until you’re uncomfortably full
- Frequently eating alone or in secret
- Feeling depressed, disgusted, ashamed, guilty or upset about your eating
- Frequently dieting, possibly without weight loss
Unlike a person with bulimia, after a binge, you don’t regularly compensate for extra calories eaten by vomiting, using laxatives or exercising excessively. You may try to diet or eat normal meals. But restricting your diet may simply lead to more binge eating.
The severity of binge-eating disorder is determined by how often episodes of bingeing occur during a week.
When to see a doctor
If you have any symptoms of binge-eating disorder, seek medical help as soon as possible. Binge-eating problems can vary in their course from short-lived to recurrent or they may persist for years if left untreated.
Talk to your medical care provider or a mental health professional about your binge-eating symptoms and feelings. If you’re reluctant to seek treatment, talk to someone you trust about what you’re going through. A friend, loved one, teacher or faith leader can help you take the first steps to successful treatment of binge-eating disorder.
Helping a loved one who has symptoms
A person with binge-eating disorder may become an expert at hiding behavior, making it hard for others to detect the problem. If you have a loved one you think may have symptoms of binge-eating disorder, have an open and honest discussion about your concerns.
Provide encouragement and support. Offer to help your loved one find a qualified medical care provider or mental health professional and make an appointment.
The causes of binge-eating disorder are unknown. But genetics, biological factors, long-term dieting and psychological issues increase your risk.
Binge-eating disorder is more common in women than in men. Although people of any age can have binge-eating disorder, it often begins in the late teens or early 20s.
Factors that can increase your risk of developing binge-eating disorder include:
- Family history. You’re much more likely to have an eating disorder if your parents or siblings have (or had) an eating disorder. This may indicate that inherited genes increase the risk of developing an eating disorder.
- Dieting. Many people with binge-eating disorder have a history of dieting. Dieting or restricting calories during the day may trigger an urge to binge eat, especially if you have symptoms of depression.
- Psychological issues. Many people who have binge-eating disorder feel negatively about themselves and their skills and accomplishments. Triggers for bingeing can include stress, poor body self-image and the availability of preferred binge foods.
You may develop psychological and physical problems related to binge eating.
Complications that may be caused by binge-eating disorder include:
- Poor quality of life
- Problems functioning at work, with your personal life or in social situations
- Social isolation
- Medical conditions related to obesity, such as joint problems, heart disease, type 2 diabetes, gastroesophageal reflux disease (GERD) and some sleep-related breathing disorders
Psychiatric disorders that are often linked with binge-eating disorder include:
- Bipolar disorder
- Substance use disorders
Although there’s no sure way to prevent binge-eating disorder, if you have symptoms of binge eating, seek professional help. Your medical care provider can advise you on where to get help.
If you think a friend or loved one has a binge-eating problem, steer her or him toward healthier behavior and professional treatment before the situation worsens. If you have a child:
- Foster and reinforce a healthy body image, regardless of body shape or size
- Discuss any concerns with your child’s primary care provider, who may be in a good position to identify early indicators of an eating disorder and help prevent its development
